MAT.

SPECIFICATION forming part of Letters Patent No. 386,434, dated July 17, 1888.

Serial No. 255,879. (No model.)

T0 all whom, it may concern:

Be it known that I, ROBERT KELSO, of Philadelphia,in the county ofPhiladelphia and State of Pennsylvania, have invented a new and valuable Improvement in Elastic Cord or Veb; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and lign res ofrefercnce marked thereon.

rPhe object of my invention is to produce a mat or similar article of composite material having a limited. amount ol' expansibility in one direction and sufficient elasticity to resume its former shape when the strain is re` moved. To this end my invention consists in a mat or similar article composed of a textile cord wound with elastic wire, said cord being folded on itself and having its lengths closely connected by the interlocking of the wire, as hereinafter set forth and claimed.

Figure l represents in perspective a mat embodying my invention, the ends being still untrimmed and nn fastened. Fig. 2 represents a side elevation in enlarged detail of a piece ofthe composite cord from which the mat is made, and Fig. 3 is a diagram representing the spiral coils of wire interlocking with each .other to bind the lengths of cord together.

A designates the composite elastic cord consisting of a textile cord or core, a, and a wire or wires, a', wound spirally thereon. rIhe core a is bent on itself, as shown in Fig. l, to forln parallel lengths, and the coils of wire or wires e in each two contiguous lengths are made to interlock, as shown in Fig. 3, the result being a complete mat, B. The core a prevents the The wire e imparts stiffness to the mat and causes it to resume its shape after strain lengthwise of the cord. The shape ofthe core may be varied, and it is immaterial Whether one wire be used, as in Fig. l, or more than one, as in Fig. 2. The mat may be used as a door-mat or a table-mat, or wherever, constituted as above described, it may be needed. Several pieces of the composite cord, A, may beattached together, if desired, instead of havling the entire mat in one piece, as shown in Fig. l.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is

A mat or similar article consisting of atextile cord wound with wire, said Acord being folded on itself and having its lengths closely connected by the interlocking ofthe wire,sub stantially as set lorth.

In testimony that I claim the above I have hereunto subscribed my name in the presence ol' two witnesses.

ROBERT KELSO.
